cos(C)= 3/4

cos (C) = \frac{3}{4}

C = 0.72273 \dots + 2 πn, C = 2 π - 0.72273 \dots + 2 πn

Solution steps

cos (C) = \frac{3}{4}

Apply trig inverse properties

C = arccos (\frac{3}{4}) + 2 πn, C = 2 π - arccos (\frac{3}{4}) + 2 πn

Show solutions in decimal form

C = 0.72273 \dots + 2 πn, C = 2 π - 0.72273 \dots + 2 πn

cos (x - \frac{π}{6}) - sin (x) = 0

2 + cos^{2} (x) = - 3 cos (x)

6 sec^{2} (x) + tan (x) - 7 = 0

4 \cdot sin^{2} (x) = 3

cos (B) = \frac{2}{3}
